Dead End?

[steveray]

New auto parts store, would you folks call this a dead end for egress purposes? I believe it is bounded by exterior wall on one side and full storage racks on the other up to a soffit (think those gravity feed oil container racks) with no real openness....Thanks!

 

[ADAguy]

A storage room, how many feet from back wall to hose nozzel?

 

[cda]

I vote NO

Would help to see more floor plan

 

[steveray]

I assume those are radiator hoses and the like on the South "wall" of oil containers...No hose nozzle...I don't think I can call it a room if it is 4' wide..

 

[Francis Vineyard]

No; IMO it's an occupiable space (storage area) with an exit access whereas dead end apply to corridors that are enclosed exit access components that serves an occupant load.

 

[Francis Vineyard]

There are no edit features and this time; add to the last sentence "from a space"

 

[ADAguy]

Is the space sprinklered?

 

[Paul Sweet]

Wouldn't common path of travel be the thing to check?

 

[steveray]

No sprinklers, CPET is <75, so that is OK. I some people view corridors as strictly traditional walls, but I am not sure I agree with that approach...

CORRIDOR. An enclosed exit access component that defines and provides a path of egress travel to an exit.

 

[Keystone]

IMO the sticking point with the definition of Corridor, "an enclosed exit". However the remainder of the definition would fit as proposed

 

[Francis Vineyard]

Generally for other than dwellings there are no minimum dimensions for rooms as long it provides for the minimum egress width and accessible route.

 

[Francis Vineyard]

Still no edit feature

I agree it is a common path of travel requirement first. If the common path of travel from the remote point of the room to a point where two different means of egress can be taken is exceeded then the back room will require another means of egress from the backroom. If it is under the common path of travel distance then there is no problem. Also if from the remote point of the room the travel distance to an exit is in compliance; then the larger space would need two means of egress because at some point out of the back room the common path of travel going into the larger space will be exceeded and two means of egress will be required.

1020.4 Dead ens. Where more than one exit or exit access doorway is required...

First question I have is 'how many exit or exit access doorways are required?'

From the building, 3......From that spot, 1. But if that was the intent you would never have a dead end because you would always have to meet CPET? and why would dead ends be a lesser distance than CPET?

Don't you calc storage spaces at 300 gross? How can you say no OL?

Because once you hit the dead end

You have to back track

Adding time and distance to getting out

 

[ADAguy]

on a parrallel note, are the racks tied down for seismic?

 

[JBI]

Dead ends are a lesser distance than CPET because CPET includes the distance from wherever you are in a building, while 'dead ends' are specific to corridors and not sending people in a direction they can't egress from. Calling a long narrow storage room a 'corridor' is, at best, a stretch of the imagination.
From the remainder of the occupancy, are there exit signs directing anyone to egress through the storage room?
If so then you have a dead end.
If not you only have CPET and travel distance to look at.

 

[steveray]

I think I am probably going to concede on this one, although I don't like the concept of a 75' long 4' wide storage room full of rubber and oil, non sprinklered with one way out.

 

[tmurray]

Under our code, corridors serve occupancies. This would be permitted under our code as well.

I agree it's certainly not ideal. I would certainly make sure proper exiting signs and lighting are provided

 

[Francis Vineyard]

Hope this illustration help clarify how dead ends are in relations to the exit access pathway within the corridors

Me neither...........

 

[JBI]

If it makes you feel any better, there are a lot of things in the Codes that I don't particularly like.
